Periodic DWScript release 22.6.28 has been created on the DWScript GitHub.
This release includes a variety of micro-optimizations (many memory-related) for the compiler, runtime and JavaScript codegen, as well as fixes and improvements.
The language syntax has been slightly extended for the Pascal-to-Javascript transpiler to cover the case of read-only external properties. (more…)
With Chrome 102 HTMLElement.inert attribute is now active, it is also in the Firefox/Edge/Safari nightlies, so will hopefully become available for those soon.
This inert attribute aims to make interactive HTML inert as a rock.
Yes, it only took 32 years to disable interactivity like in HTML 1.0, hurrah!
To quote MDN:
The HTMLElement property inert is a boolean value that, when present, makes the browser “ignore” user input events for the element, including focus events and events from assistive technologies.
So it is like good old Enabled from the VCL. And this is a great addition to HTML! (more…)
cefHtmlSnapshot 0.8.101 release is now available on the cefHtmlSnapshot repository.
This version uses CEF 101.0.15 which includes Chromium 101.0.4951.54, and is recommended for production, as it fixes multiple zero-day issues being actively exploited.
Output formats of text type have been added, you can now output a plain text, HTML or console content snapshot.

cefHtmlSnapshot 0.7.100 release is now available on the cefHtmlSnapshot repository.
This version uses CEF 100.0.23 which includes Chromium 100.0.4896.127, and is recommended for production, as it fixes multiple zero-day issues being actively exploited.
The bundled turbojpeg is updated to 2.1.3, though only to keep up as none of the security and fixes issues applied here.
Finally this version disables the Back/Forward cache, which may not have any effect, but was unnecessary.
The DWScript JavaScript code generator is now transitioning to ECMA6, as the the LTS versions of browsers are now completing the transition. So you will now see the code generator using “let” and other ECMA6 constructs where they make sense, in terms of performance or compacity.
Just downloaded and installed Delphi 11.1, and all the unit tests passed without a glitch. So I can announce that DWScript is compatible with Delphi 11.1 for Win32 and Win64! You can find links to all the Delphi 11.1 release details on Marco’s blog.
In other news, the tip of the DWScript repository is considered stable, but a round of core changes were made a few days ago. The last stable state just before the round of changes can be found in the DWScript Releases on the GitHub mirror. The next round of changes likely be able to will rip out the stack from the engine, and transition to closures.
After rediscovering DelphiCodeCoverage, I had made a few cosmetic and functional upgrades to its HTML Report.
I have now pushed a few more rounds of upgrades for better looks and usability. In case they are not merged or you want to test run future changes, you can check my fork of the repo, though for stability stick to the official repository maintained by ekot1.
Here is a visual summary of the changes, form original state to current one. (more…)
As a bunch commits were just made, it is a good opportunity for a spotlight on dwsDateTime and TdwsFormatSettings.
The class was initially born out of two needs:
Recently noticed DelphiCodeCoverage had a new home on GitHub, with several updates that make it stable. I had been it in a previous incarnation to assess DWScript test coverage, and help pick which aspects of the engine were in need of extra tests.
The DWScript tests can be quite heavy on exceptions, sub-processes and multithreading. The tests go after checking all things that should fail do fail as they should. That was a bit too much stress for the previous versions, which would occasionally crash. I am happy to say those issues are gone from the current version of DelphiCodeCoverage!
When a double is neither greater nor lesser, is it equal ?
This is assumed in some implementations like for RTL’s VarCompareValue and other function that return the result of the comparison.
In those function you can see code like (more…)
